3 Claims.

This invention relates to safety release devices -for power drivenwringers of the type conventionallyused in connection with domestic washing machines. 5 The main object of the invention is to provide a wringer having releasable means associated with the upper roll for holding the roll stationary to sustain contact pressure between the upper and lower rolls.

Another object is the provision of yieldable means for abutting the lower roll against the upper roll.

A further object is to provide a mechanism for holding the upper roll in such a manner that the is upper roll may be quickly and conveniently placed in contact with or removed from the lower roll.

Still another object is to provide a manually operable means whereby the upper roll supporting mechanism may be actuated to remove or re-, place the upper roll from contact with the lower roll.

. Other objects will appear in the accompanying description and drawings, in which- Fig. 1 is a side elevational view of a wringer 26 which embodies my invention, with certain parts shown in section, to facilitate description; Fig.2isaplanviewoftheunitshown inFig. 1; Fig. 8 is an end elevational view of the wringer shown in Fig. 1; Fig. 4 is an end elevational view taken from line 4-4 in Fig. l; and

Fig.5 isaviewsimilartothatshowninFig.4 showing parts in operated position.

Referring to the drawings, Fig. 1 will disclose a U.-shaped supporting frame member 10 of hollow cross-section, to the upstanding ends of which are attached supporting bracket members 11.

Disposed between the ends of frame 11 is a lower wringe'r roll 12 and an upper roll 13. 1

The shaft 14 of lower roll 12 is rotatably supported in bearing blocks 15. Blocks 15 are disposed within the body of frame 10 and are slidably mounted upon rod members 16, which are secured to and depend from inwardly extending lug portions of brackets 11, as best shown in Fig. 3. Retained upon rods 16 by means of nuts 17 and cross members 18,. are compression springs 19 which react between nuts 17 and blocks 15 to urge roll 12 upwardly.

Shaft '14 of roll 12 is adapted at its left hand end, as viewed in Fig. 1, to receive a coupling member whereby it is connected with driving means, which being no part of this invention, will .55 not be described. 4

The upper roll 13 is provided with a bushing member 20, whereby the roll is rotatably supported upon a shaft 21, which shaft is rotatably supported in link members 22, the latter being pivotally supported upon studs 23 which are secured in brackets 11, as shown.

Pinned upon shaft 21 are lever members 24 having forked lower extremities as at 25 in Fig. 4, the forks being adapted to engage stud members 26 secured in brackets 11.

A hand rail 27 is secured, at either end, to levers 24 by means of shouldered portions 28 and nuts 29. Slidably mounted in circular cavities in each of levers 24 and disposed adjacent the hand rail 2'7 are plunger members 30, the extending ends of which are adapted to engage indent portions 31 formed in the upper periphery of links 22 as more clearly shown in Figs. 4 and 5. Compression springs 32 retained within the cavities above plungers 30 tend to urge the plungers into en- 76 gagement with indents 31.

Operation of the mechanism is as follows:

Link 22 is adapted, when positioned in vertical alignment with the axes of shafts 14 and 21, as shown in Fig. 4, to retain the upper roll 13 in a 80 lowered position in pressure contact with lower roll-12, the pressure being supported between nuts 17 and studs 23 through springs 19, blocks 15, shaft 14, rolls 12 and 13, shaft 21 and links 22.

Levers 24, when positioned in alignment with links 22, are adapted to hold the links in retaining position, as described, by means of shaft 21, engagement of forks 25 with stationary studs 28 and engagement of plungers 30 in indents 31.- With the parts arranged as described, the mechanism is adaptedto operate as a wringer.

Reference to Fig. 5 will illustrate that slight manipulation of the hand rail 27 toward either side of the wringer will rock levers 24 to dislodge plungers 30 from indents 31 and, with studs 26 as fulcrums, rock links 22 upon studs 23 to displace links 22, together with shaft 21, from dead center alignment previously described. Thus, the links are rendered incapable of retaining roll 13 in abuttingrelation to roll 12 and pressure between the said rolls is removed.

Re-arrangement of the parts into working position is accomplished by manual replacement of hand rail 2'7, with levers 24 in upright aligned whereby the roll, is swingably mounted in links mounted upon the supporting frame, separ t manually operable levers adapted to co-opera with the shaft and links to bring about swinging movement of the shaft and roll, means associated with the levers and links for retaining the said levers in position to retain the upper roll in 0pposing relation with the lower roll, and a hand rail associated with said levers for convenient manipulation thereof.

2. A wringer mechanism having in combination upper and lower rolls, a supporting frame therefor, means for supporting the lower roll in yieldable opposing relation to the upper roll, means for supporting the upper roll in such a manner that it may be swung into and out of opposing position relative to the lower roll and retained in opposing position, the said supporting and retaining means comprising links pivotally mounted upon the upper portion of the supporting frame, a wringer roll shaft mounted in said links, levers mounted upon said shaft and rockable about the center thereof, one end of said levers adapted to be fulcrumed at a point located between the centers of the upper and lower rolls,

the levers being adapted, when rocked about the renter of the shaft, to swing the rollv about the pivotal center of the links, to move the roll into or out of contact with the opposing roll.

3. A wringer mechanism having in combination a supporting frame, lower and upper rolls supported thereby the lower roll supported in yieldable opposing relation to the upper roll, the upper roll rotatably mounted upon a shaft supported at both ends by means of links swinga-bly supported upon the frame at a point above the roll, lever members upon the shaft pivotally supported intermediate their ends adjacent the link members, the lower ends of the levers adapted to engage a portion of the frame disposed intermediate the centers of the rolls whereby the levers NICHOLAS L. m.
